The specs from IGI

At the top of this page there is a Resources link which will provide access to the Holloway Cut Adviser, it is helpful as an initial screening tool in terms of diamond cut and potential performance, here are the results for this diamond:

Hey Todd,

Thanks for this quick reply.

How would you rate a price tag of $12,500? Fair, on the high or low side?
 
HI DrBranDo

In my opinion, a stone of this grade should only be considered if the grading is done by GIA or AGS. This is for YOUR protection.
Non GIA labs are notorious for inaccurate grading.

I''m kind of limited in what I can say about the proportions of the diamond or the price due to the fact that I am considered a competitive vendor; so what I''ll do is direct you to the diamond search feature provided on the front of this web site... When I conducted a search for a diamond of this carat weight, color and clarity and limited the total depth field to an exact match (63.7%) I was able to find an option (from a vendor other than myself) which will provide you with some insight. Note that I left the fields for Table Diameter at the PS default settings.

Ditto what David from DBL said, I''m partial to grading provided by the GIA, AGS or HRD (Belgium) laboratories.

Impossible to say.
If you sent it to GIA or AGS it would almost certainly come back with grades worse than G VVS1.
How much worse?
Maybe one grade or two, maybe three, or four.
Nobody knows.

Price depends on grades.
If grades are uncertain then the price is a crap shoot.
When you gamble the odds are with the house.

So there are two reasons to NOT buy this diamond.
It scored over 2.0 on the HCA and nobody knows what the true clarity and color grades are.

Stick with AGS or GIA-graded diamonds so you know what you are getting.
 
That is on the high side. You can get an AGS Ideal from JA for $9,440 with the same specs, and possibly cut better. http://www.jamesallen.com/diamonds/G-VVS1-Ideal-Cut-Round-Diamond-1197032.asp?b=16&a=12&c=77&cid=131

Or a beautiful ACA from WF that is a VVS2 for 9200 http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-2231172.htm

For 12K you can get up to a 1.27 ct http://www.jamesallen.com/diamonds/G-VVS1-Ideal-Cut-Round-Diamond-1248002.asp?b=16&a=12&c=77&cid=131with the specs. I am sure experts have more, just some for thought.
 
This stone is too deep (for one thing). Should be measuring around 6.5 mm for a well cut 1 carat. You are down at 6.3ish mm.
Depth should be between 60-62% (others have numbers that are slightly different).
 
Thanks for all the info guys.

It''s definitely expensive if I compare with the links sent by Horton and insight from Todd.

I definitely have to do more research.

It''s kind of scary to buy a diamond online but I do understand it''s more value for money.

How safe is it buying from these websites:
http://www.jamesallen.com
http://www.whiteflash.com/
www.bluenile.com

I''ll keep the GIA and AGS comment kenny. :)

Thanks again
 
There are alot more experienced buyers on here besides me, but I felt totally safe buying online. I just bought from Whiteflash and received the ring yesterday. It is absolutely beautiful and I got a great deal. So happy i bought online. I wouldn''t hesitate to buy again from them. Even though I have only dealth with Whiteflash, i would feel comfortable buying also from others JA, Brian Gavin, etc. All respected PS vendors will have great return policies.

Lots of people buy on-line these days. Those sites you listed are very reputable. I'm going to give you a few more to take a look
at...

Plus, when you come to PS, you get lots of advice/opinions from people who have spent many years buying/studying diamonds.

My preferred range is "super tight" maybe to the point of insanity, but I''ll provide it as a reference point in order to provide some insight into how far the diamond originally mentioned is off from something which I might consider (there is some middle ground, personal preference and all that, so I''m not saying "only this will do", to each their own and all that):

Total depth: 59 - 61.8%
Table diameter: 53 - 57%
Crown angle: 34.3 - 34.8 degrees
Pavilion angle: 40.6 - 40.9 degrees
Girdle: thin to medium, slightly thick acceptable.
Culet: GIA none or AGS pointed

That said, would I kick a 34.0 crown angle offset by a 40.8 pavilion angle out of bed; not likely - the pavilion is the primary reflective surface in terms of directing light back up towards the observer and I rather like a 40.8 pavilion angle - so I''d keep the diamond in the consideration pile... But a steep crown (such as 36 degrees) offset by a steep pavilion angle (such as 41.0+ degrees) is not appealing to "my eyes" and visual preference; so I wouldn''t give it a second glance - but somebody else might.

There is a lot of knowledge to be gleaned from the Knowledge section of this forum Dr. B, so spend some time reading before you pick a diamond, you''ll be glad that you did!
 
Wow I just try the HCA grading for the link sent by Horton

http://www.jamesallen.com/diamonds/G-VVS1-Ideal-Cut-Round-Diamond-1197032.asp?b=16&a=12&c=77&cid=131

And the results were excellent everywhere except Spread with a Very Good rating.

HCA 0.7 Price at $9,720

The one I looked at today was HCA 5.7 priced at $12,500.

what a good feeling to be $3k richer and a better diamond in hand. :)

Oh no, more websites to browse from tyty333. Now I have to read on the websites to know which one is more suitable :-S Thanks tyty333.

Last question: Any preference/difference/advantages/disadvantages on 4 or 6 prongs?
 
most of us here buy online from one or more of these vendors.

Included your list are
HighperformanceDiamond.
NiceIce.
GoodOldGold.
BrianGavinDiamond.
IDJewelry.
ExcelDiamond.
EngagementRingDirect.
UnionDiamond.

I'll weigh in in this question with a picture of my ring. This just happened a few days ago and I never felt the blow that sheared the prong. With only 4 prongs I really think I'd have lost a stone I don't think I can replace.

No pictures yet. Still being shipped. :) I went for the tension setting. Hopefully they are ok.
